Why do engines have balance shafts?
[149 Pages Report] A balance shaft is designed to rotate and vibrate in a way that reduces the vibration produced by an engine. Balance shafts are commonly used for engine refinement. Four cylinder engines use a tow shaft, which turns in opposite directions on either side of engine’s crankshaft.
What’s the best way to balance a drive shaft?
Ask your assistant to step on the brakes gently, then turn the engine off. Install two hose clamps side by side onto the drive shaft, aligning the screw assembly 180 degrees opposite the chalk mark. Tighten the clamps. Ask your assistant to turn the engine on again and accelerate to 40 to 50 mph.
What are the dimensions of a balance shaft?
The amount of vibration also increases with engine displacement, resulting in balance shafts often being used in inline-four engines with displacements of 2.2 L (134 cu in) or more.
Where does the balance shaft run on a Ford Taunus?
Valve timing gears on a Ford Taunus V4 engine. The balance shaft runs off the small gear on the left (the large gear is for the camshaft, causing it to rotate at half the speed of the crankshaft).
How is a balance shaft used in a V4 engine?
Balance shaft in Ford Taunus V4 engine. Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force.
What kind of screwdriver do I need to lock balance shaft?
Inset a Phillips screwdriver with a shank diameter of 8mm (.32 in.) into the plug hole to lock the balance shaft. Check to be sure that the screwdriver goes in 60 mm (2.36 in.) or more.
How do you remove a balance shaft from a car?
1. Remove timing belt, downpipe, transfer case and oil pan. 2. Remove alternator, power steering pump, cross member, front and left motor mount to drop the engine low enough. 3. Remove the front case with the left balance shaft attached. This involves pulling the crank shaft sprocket and everything else over the front case. 4.
Which is the front end of a balance shaft?
You can use the balance shaft’s front end since it has a larger diameter than the rear bearing. The left balance shaft bearing can be eliminated since the oil is fed through the shaft and not from the block. 5. Stub shaft install Use red Loctite or equivalent! Install the oil pump gears so that the timing mark are shown.
How to remove balance shaft from oil pan?
3. Balance Shaft Removal Remove the plug bolt located under the 3rd cylinder freeze plug about 2 inches above the oil pan. Inset a Phillips screwdriver with a shank diameter of 8mm (.32 in.) into the plug hole to lock the balance shaft. Check to be sure that the screwdriver goes in 60 mm (2.36 in.) or more.
